Abstract: Firstly different fatigue testing methods of HMA were summarized, the scope of applicability of two kinds of control mode were analyzed, it is recommended that indirect tensile fatigue test with stress control mode to be ...

Abstract: A research was performed for crack pathology of prestressed concrete box girder bridge (PCBGB). Cracking information of PCBGB in national scope was collected and investigated. Main crack types, distributing pattern and ...

Abstract: A theory for directly identifying shrinkage and creep in a structure, along with an embedded self-identification system, is proposed. The theory and system aim to obtain accurately the time-dependent regularity of shrinkage ...

Abstract: The long-term deflection of Long Span Prestressed Concrete Box-girder Bridge (LSPCBB) is getting more and more serious in terms of structure safety. And there are still many ambiguous reasons as to the cause of the deflection ...

Abstract: To study the fatigue prestress loss of prestressed concrete beams, four bonded post-tensioned bonded concrete simple supported beams were designed and constructed for constant-amplitude fatigue load displacement tests. ...

Abstract: To investigate the laws of creep and shrinkage in high-strength, concrete for long-span prestressed continuous box-girder bridge and predict long-term deflection, strain sensors were embedded in the midspan of a box-girder ...

Abstract: Underground coal gasification (UCG) is a highly efficient new type of coal mining technology with broad future prospects. In order to study the cavity extension formation in the early ignition stage of UCG, a block coal ...
